Pinpoint Test AQ: P0C6A

  1. NOTE: The Secondary Inverter System Controller (S-ISC) is referred to as the SOBDMB (Secondary On-Board Diagnostic Control Module B) in the scan tool.

    Normal Operation and Fault Conditions 

    REFER to: Front Electric Drive Assembly - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    SOBDMB P0C6A:00 Generator Position Sensor Circuit "B" Range/Performance: No Sub Type Information This DTC sets when a the resolver-to-digital converter reports a conversion fault.

    Possible Sources 

    • Wiring, terminals or connectors
    • Secondary Inverter System Controller (S-ISC) calibration
    • Secondary Inverter System Controller (S-ISC)

  2. AQ1 CHECK FOR SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, check for Secondary Inverter System Controller (S-ISC) CMDTCs.

    Are any Secondary Inverter System Controller (S-ISC) CMDTCs other than P0C6A present? 

    Yes  DIAGNOSE all Secondary Inverter System Controller (S-ISC) CMDTCs, REFER to Diagnostic Trouble Code (DTC) Chart .
    No  For DTC P0C6A only, GO to  AQ2

  3. AQ2 CHECK THE SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) CALIBRATION LEVEL

    NOTE: Wiring overlays or repinning of circuits are NOT appropriate for DTC P0C6A due to risk of hardware damage.

    • Verify the Secondary Inverter System Controller (S-ISC) is at the latest calibration level.

    Is the Secondary Inverter System Controller (S-ISC) at the latest calibration level? 

    Yes  GO to  AQ3
    No  UPDATE the Secondary Inverter System Controller (S-ISC) to the latest calibration level.

  4. AQ3 CHECK FOR SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, run the Secondary Inverter System Controller (S-ISC) (SOBDM-B) self-test.

    Was DTC P0C6A read from the Secondary Inverter System Controller (S-ISC)? 

    Yes  GO to  AQ4
    No  The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

  5. AQ4 VISUAL INSPECTION OF THE LOW VOLTAGE SYSTEM

    • Ignition OFF.

    • Visually inspect all the low voltage cables.

    • Make sure all the low voltage connectors are correctly and securely connected.

    • Examine all the low voltage cables and connectors for damaged, burned or overheated insulation and loose or broken conditions.

    Is a concern present? 

    Yes  REPAIR as necessary. CLEAR the Secondary Inverter System Controller (S-ISC) DTCs and REPEAT the self-test.
    No  CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new Secondary Inverter System Controller (S-ISC). REFER to: Inverter System Controller [SOBDMB] .
